While I'm here - I recently optimized our PR review skill to make better use of the KV cache. Previously, it loaded up the diff, persona and prompt, and wrote those into the first …

I'm begging people to write articles themselves rather than letting Claude do it for them. I want an expert opinion, if I just wanted to ask an LLM I have my own. How can this arti…

> There are people who do, - And there are those who criticize. There’s no need for that. I’ve done plenty.

Is it on topic to complain about the various claude-isms in this article? I don't know any actual humans that write titles like "Two floors the rate card hides". I find my brain di…

They sort of are, in that they want subscription users to have clients that behave well with the KV cache etc. If you don't use a subscription, and pay per token instead, you can e…

A family member stayed in a hotel in Dubai recently and on returning said how incredible the staff were and willing they were to help them, and my response was "no shit"

Nothing has changed, just OP found the mirror of the main repo with the ee/ folder removed. That repo has been up for most of the lifetime of the company.

PostHog has always been open source. I'm not sure why this has been shared on HN at all.

That's valid criticism, I kinda hand-waved the "months" part. I read everything I could about parsers while building this (I have a CS background but hadn't thought about parsers i…

The previous parser is mostly a declarative grammar file, which is extremely readable. It codegens a C++ parser, which is hard to read. It depends which of those you count as the p…

Yeah, one of the interesting parts to me while working on this is that the breakpoint for when it's worth writing your own parser vs accepting ANTLR's slowness has shifted massivel…

:D I was hoping to avoid the criticism that I was picking the most favourable number and being misleading!

In what way? This was a geometric mean of the improvements from a small test corpus. In production, where it only parses longer SQL that didn't hit the parser cache, the mean parse…

Ha I did consider that! But 70x is plenty fast enough (we still have to query an actual database!) and the parser runs in a shared process on untrusted input, so it wasn't worth th…

It took about 2 days to get a proof of concept, and about a week to get something I could ship to production. I skipped a few features for the PoC (like XML tag support, token posi…

Our SQL is very similar to ClickHouse SQL, in that we used ClickHouse SQL as a starting point as that's what our underlying DB is. We needed to have our own parser so that we could…

We pay github quite a bit of money and it's down for us too

I did that first, which didn't work for a couple of reasons. Many "big and tall" stores are the intersection only, and many of the stores didn't quite have the right vibe. I do hav…

Undecided. One of the sites didn't have an LT but the LLM flagged that chest dimensions on their large were narrower than others, so could be worth trying.

Huh, I shopped for clothes using AI today. Not super relevant to the Googlebook ad, but in case the perspective is interesting to you: I'm quite tall (194cm) but not very wide, so …

Wait - are you missing all the context on this? Anthropic pushed back against this hard, there was a whole back and forth. I'm on mobile and can't look it up for you atm but if you…

Quite a lot worse. Both OpenAI and xAI were among the largest donors of Trump's campaign Musk was the largest individual political donor of the 2024 election [1] and Greg Brockman …

There's proof of financial dependence, here's a recent report https://assets.mozilla.net/annualreport/2021/mozilla-fdn-202... In 2021 they got $500M "royalties" (this is their paym…
